Question about engine port prioritization

[Chaiyoabc]

Since latest update, i have seen that there has been many premade port prioritization profiles such as unreal engine, source engine, etc

i have been wondering what port do those engines use? May be dev could breakdown a lil bit for this? 
 

thanks

They will be using deep packet inspection to detect when these services are being used, rather than being triggered by ports - other than the Games Console service which can't use DPI and uses 1024-65535.
